Book Description
As food and animal protein demand increases, black soldier fly larvae (BSFL) meal has gained interest in the past couple of years for use in animal feed as an alternative protein ingredient. Black soldier fly larvae is an attractive protein source; however, it is important to evaluate its amino acid (AA) digestibility and metabolic availability (MA) before incorporation in feed formulation. The global objectives of this thesis were to determine the standardized ileal digestibility (SID) coefficient of AA and MA of methionine using the indicator AA oxidation (IAAO) method from BSFL meal, and to compare the results from the two protein quality methodologies. The SID coefficient of indispensable AA in BSFL meal was found to be above 83%, while the MA of methionine was found to be 53.33%. This finding further confirms that SID coefficient tends to overestimate AA bioavailability and that MA is a more accurate representation of bioavailability.

Book Description
Aquaculture now supplies half of the seafood and fisheries products consumed worldwide and is gaining international significance as a source of food and income. Future demands for seafood and fisheries products can only be met by expanded aquaculture production. Such production will likely become more intensive and will depend increasingly on nutritious and efficient aquaculture feeds containing ingredients from sustainable sources. To meet this challenge, Nutrient Requirements of Fish and Shrimp provides a comprehensive summary of current knowledge about nutrient requirements of fish and shrimp and supporting nutritional science. This edition incorporates new material and significant updates to information in the 1993 edition. It also examines the practical aspects of feeding of fish and shrimp. Nutrient Requirements of Fish and Shrimp will be a key resource for everyone involved in aquaculture and for others responsible for the feeding and care of fish and shrimp. It will also aid scientists in developing new and improved approaches to satisfy the demands of the growing aquaculture industry.

Book Description
Wheat is the primarily cereal grain produced within the European Union. Due to its high starch content it is the dominating energy feed ingredient in diets for pigs. However, due to its high dietary inclusion level wheat can also supply considerable high amounts of crude protein (CP) and amino acids (AA) to the animal. Wheat co-products of bioethanol production are a valuable source of CP and AA in animal nutrition. Therefore, the objectives of the present thesis were to study the nutritive value of eight recently introduced wheat genotypes and of one liquid wheat co-product of bioethanol production for growing pigs. For this purpose a comprehensive analysis of nutrients in the assay feedstuffs was conducted and standardized ileal digestibility (SID) of CP and AA in growing pigs was determined. There were significant differences in SID of CP and AA between the eight genotypes of wheat. However, digestibility values were lower when compared to literature data, leading to the assumption that data in actual feed tables might result in an overestimation of the protein value of wheat. The liquid wheat co-product is a valuable source of CP, AA and energy in diets for pigs. It is superior to dried bioethanol co-products as it is not exposed to excessive heat treatment during manufacturing resulting in greater digestibility values. In der Europäischen Union ist Weizen die am weitesten verbreitete Getreideart. Aufgrund seines hohen Stärkegehalts wird Weizen in Mastschweinerationen als Energiefuttermittel eingesetzt. Bei hohen Anteilen in der Gesamtration kann Weizen jedoch auch einen erheblichen Beitrag zur Deckung des Rohprotein- (XP) und Aminosäuren (AS)- Bedarfs des Tieres leisten. Nebenprodukte aus der Weizenverarbeitung bei der Bioethanolproduktion sind eine wertvolle Eiweißkomponente in der Tierernährung, dazu zählen Trocken- und Flüssigschlempen. Ziele dieser Arbeit waren die Bestimmung des Futterwerts von 8 aktuell verfügbaren Weizengenotypen sowie eines flüssigen Weizenschlempefutters für Mastschweine. Zu diesem Zweck wurde eine umfangreiche Nährstoffanalyse der Versuchsfuttermittel durchgeführt, sowie die standardisierte praecaecale Verdaulichkeit (pcVQ) von XP und AS bei Mastschweinen untersucht. Es gab signifikante Unterschiede der pcVQ von XP und AS zwischen den 8 Weizengenotypen. Allerdings waren die Verdaulichkeitswerte geringer als in der Literatur angeben, so dass Daten aus aktuellen Futterwerttabellen möglicherweise den Proteinwert von Weizen überschätzen. Das flüssige Weizenschlempefutter stellt eine wertvolle XP-, AS- und Energiequelle für Schweine dar. Es ist Trockenschlempen im Nährwert überlegen, da es keiner intensiven Hitzeeinwirkung ausgesetzt ist und somit höhere Verdaulichkeitswerte aufweist.

Book Description
Cereal grains, such as rye and triticale are a major source of energy in pig nutrition. The crude protein (CP) content in cereal grains is rather low compared to protein ingredients such as soybean meal. However, costs and availability of soybean meal are strongly correlated with the price development of agricultural commodities on the world market. Therefore, swine producers will make increasing efforts to use protein from locally produced cereal grains more efficiently to reduce feed costs. Measurements of apparent (AID) and standardized ileal digestibility (SID) of CP and AA are frequently used to estimate the amounts of absorbable AA from the diet which are used for pigs’ metabolic processes. However, until now there is limited data on SID of CP and AA in rye and triticale, particularly in new genotypes. Therefore, one objective of the present work was to determine the variation in nutritional composition and SID of CP and AA of 8 currently available rye and 8 triticale genotypes. Standardized ileal digestibility of CP and most AA between the 8 assayed genotypes of both rye and triticale did not differ. Furthermore, average SID values of CP and AA of both rye and triticale in the present experiment were lower when compared to values of rye and triticale published in current feed tables. Thus, future research should clarify, whether these differences in comparison to feed tables are caused by experimental conditions or reflect a consistent decrease that need to be accounted for in feed tables.

Book Description
A cautious assessment of standardised ileal digestibilities (SID) of crude protein (CP) and amino acids (AA) as a measure to describe AA bioavailabilities is critical for evaluating the protein value of feed ingredients for piglets. Estimates of SID have been generated for most feed ingredients for grower-finisher pigs, whereas corresponding values for piglets hardly exist. Until now, SID values determined in grower-finisher pigs are used in diet formulation for piglets as well. However, there is some concern that these values may not be valid in piglets due to a limited digestive capacity for feed protein in piglets. A guideline for the standardisation of the experimental procedure in digestibility experiments had already been proposed for grower-finisher pigs. These guidelines firstly include threshold levels for CP and AA in the assay diets to obtain so-called plateau apparent ileal digestibility values, which are independent of dietary CP and AA levels, and secondly values for IAALB. For piglets, similar guidelines, including dietary threshold levels and values for IAALB, have currently been established. Therefore, the objective of the thesis was, based on these guidelines, to determine SID of CP and AA in 24 assay feed ingredients, including 11 products from soybean processing, 7 by-products from starch processing, 2 fish meals and 4 whey proteins. For this purpose, a total of 4 digestibility experiments with piglets fitted with simple T-cannulas at the distal ileum was conducted. For each experiment, 14 barrows were weaned at 18 days of age. Each experiment consisted of 3 periods for digesta collection. A total of 24 semisynthetic cornstarch-based diets with various inclusion levels of casein were formulated to which 1 of the 24 assay feed ingredients each was added. The daily feed allowance was restricted to 30 g/kg of individual body weight throughout all experimental periods. The SID values were determined by difference to SID values in casein. The results of the present studies show large variations in SID values among differently processed soybean products (p0.05). The SID values in extruded soybeans (SBe) were lower compared to high-protein soybean meal (SBMhp), soy protein concentrate (SPC) or partially hydrolysed soy protein isolate (SPIh) (p0.05). Aqueous alcohol or water extraction in SPC or SPIh improved SID values compared to SBMhp (p0.05). The SID values among the 4 batches of SPC were similar (p0.05) and consistently high. Moreover, the SID values were similar in SPC and SPIh (p0.05). The SID values of in alternatively processed soy proteins including enzymatically fermented SPA and microbially fermented SPB, were inconsistent. For the 3 SPA products, SID increased numerically from values similar to SBMhp to values similar to SPC with increasing duration of enzymatic treatment. For SPB SID values were low and similar to SBe, which may be attributed to protein denaturation during microbial fermentation. The results of present study show for most AA similar SID values for all by-products of starch processing including pea protein (PeaP), wheat gluten (WG), corn gluten (CG), and potato protein (PotP) compared to SPC (p0.05) except for SID of Lys in WG and CG, and SID of Trp in CG were considerably lower compared to other products (p0.05). The particular low SID of Lys and Trp in WG and CG might be simply a reflection of an experimental error, because SID values by means of the difference method rely on sufficient high AA contribution levels to the assay diets, which was not achieved for the aforementioned AA. The results of the present study show that SID values in fish meal (FM1) and extracted fish meal (FM2e) vary considerably (p

Book Description
Increased global meat consumption has led to an increase in livestock production. While the demand for output increases, so has the need for alternative protein sources in feed to minimize the environmental impact of livestock production. Insect protein is a potential alternative to conventional sources of protein (e.g., soybean meal or cottonseed meal) for cattle consuming low-quality forage (LQF). The use of insects as livestock feed has been documented in the literature, and interest is growing; however, the Association of American Feed Control Officials (AAFCO) has only approved the use of dried black soldier fly larvae (BSFL) for salmonid, poultry, swine, and adult dogs. The objective of this experiment was to evaluate the use of Black Soldier Fly Larvae meal (BSFLM) and BSFL frass and larval sheddings (FRS) as novel supplemental proteins for beef steers consuming low-quality forage. Eight ruminally fistulated steers (240.2 ± 22.5 kg of BW) were used in replicated 4 × 4 Latin squares. One of four treatments were provided to each steer per period: a control (CON) with no supplement, cottonseed meal (CSM), partially defatted BSFL meal (BSFLM), or BSFL frass and larval sheddings (FRS). Four 16-day periods were conducted with an 8-d adaptation to treatments, 7-d measurement of intake and digestion, and 1-d collection of ruminal fermentation and microbial samples. Dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) were determined for forage, supplement, ort, and fecal samples. Microbiome analysis of microbial communities' composition was conducted using 16S rRNA sequencing for liquid and solid rumen fractions. Protein supplementation of CSM, BSFLM, and FRS increased forage organic matter (OM) intake (P
